[SOLVED] How to use jq to merge a list of dictionaries into one dictionary

How to use jq to merge a list of dictionaries into one dictionary

I'm developing jq expressions on the command line. (I plan to use the expression with pyjq in python to parse http requests.)

The following command line:

$ cat some.json | jq '.collection.rows[].rowAnswers | map({ (.refCode) : .answers[0].responseText }) '

Results in two items.

[
  {
    "NAME": "some_name1"
  },
  {
    "CODE": "code1"
  },
  {
    "SERVER": "server1"
  }
]
[
  {
    "NAME": "name2"
  },
  {
    "CODE": "code2"
  },
  {
    "SERVER": "server2"
  }
]

This is a nice intermediate step. I'd like to merge each list of dictionaries into one dictionary. I'd like the final result to be:

{
    "NAME": "some_name1"
    "CODE": "code1"
    "SERVER": "server1"
}
{
    "NAME": "name2"
    "CODE": "code2"
    "SERVER": "server2"
}

If that's too difficult, then [merge_dict][merge_dict] is good too.

There won't be any key collisions. Also, this is simplified output. I'd like an expression that merges all kv-pairs into one dictionary. I don't want to hardcode the actual name of the keys in the expression.

Thanks.

Solution

Based on your description, it would seem that could achieve what you describe as your "final result" just by adding add to your pipeline.
